Deleting Functions

Folks,

I am using PGSQL do do all of my schema changes, but have run into a 
problem.  I need to be able to DROP all of the USER FUNCTIONS that are 
defined in a schema.  The problem is that I do not know the names of all 
of the functions and parameters.  I know that I could use '\df' and then 
use perl or some other scripting language to parse this, but I need to 
be able to perform this action on multiple platforms (without rewriting 
the process for each platform). 

I have written a script that incorporates '\df' and appropriate parsing 
to perform this action for LINUX and it works fine/lasts a long time.  I 
need to make this more transparent so it will run on all platforms (in 
particular windows).

I know that in the past (version 7) there was a way to drop the 
functions by directly accessing some of the system tables.  The 
question/problem is that we have updated to version 8.1 and need the 
same functionality.



Any help or directions would be greatly appreciated.

Thanks Scott.
